WASHINGTON COUNTY, Penn. - The Madison County Sheriff's Office says the Florida murder suspect last seen in north Alabama is dead following an encounter with police in Pennsylvania.

According to Pennsylvania State Police Troopers, at approximately 11:22 Thursday night, authorities conducted a traffic stop near Interstate 70 for 'erratic driving.' As Troopers made contact with 45-year-old Steven Brooks, they say he drove off and troopers pursued.

Police say Brooks traveled off the roadway, striking a concrete bridge pillar. The police account is that Brooks left his vehicle, refused commands from Troopers, and ran away, scaling a fence.

Once police followed him, they say Brooks showed a firearm and turned towards Troopers with the weapon in his hand. Law enforcement say that when they asked Brooks to drop the weapon, he wouldn't.

Steven Brooks was at the center of a three-hour standoff in Harvest Wednesday night before he is believed to have plowed through a police blockade and escaped.

The Madison County and Limestone County Sheriff's Offices assisted the US Marshals Service in searching a perimeter in northwest Madison County on Thursday. Authorities flew a helicopter and used K-9 units to search a mile and half area near where they say Brooks ran into the woods.

Florida court records show he has an extensive rap sheet, spending the last two decades in and out of prison. Brooks was convicted of third-degree murder in 1991. Since then, he's also been convicted on a number of violent felonies.

Florida court filings from this month show he was behind on his rent and was going to be evicted.
